keruig users using a refilible cup for folgers vs folgers k cups is there actual taste diffrences

OK my aunt drinks the Folgers black silk kcups which seem to be the most expensive ones in existence but being inspired by this thread: https://boards.straightdope.com/sdmb/showthread.php?t=874777
I’m thinking of just getting a dollar tree 2.0 compatible refillable one and buying a normal can but since I’m the one actually making it my question is: is there enough of a taste difference to go through the hassle of filling it every time she wants a cup? if so then ill go that route, because what she pays for 12-16 k cups I can get a 48 oz or larger can …

also whats the best reusable cut to buy for a 2.o?

an oops post …

trying again …

I don’t have experience with Folger’s, but here’s my reusable K-cup anecdote:

Our company switched from providing free K-cups to still providing the machine but we had to provide the cups. I ordered a highly-reviewed refillable cup from Amazon, and tried various levels of filling with Dunkin’ Donuts ground coffee. At any level, I could not get the strength strong enough to match the Dunkin’ Donuts own K-cup. I prefer fairly mild-medium strength coffee, and it really wasn’t close.

But: the vast majority of Amazon reviewers of the product really liked it, so maybe it’s worth a try.
